Modest Leganes face Real Madrid in Copa del Rey

Messi grabbed the opening two goals in the 13th and 15th minutes, both finished with a sublime first touch with his left foot, both created by Jordi Alba.

Luis Suarez made it 4-0 before halftime, while Messi was replaced by Ousmane Dembele before the hour mark.

Suarez nearly capped the win with a spectacular chip from 40 yards, with the ball just sailing wide of the left-hand post, but Rakitic added gloss to the scoreline three minutes from time with a firm header from Dembele's corner.

Celta drew 2-2 in the Camp Nou in the La Liga earlier in the season and held Real Madrid to a 2-2 draw on Sunday. The Brazil midfielder will make his debut after he recovers from a right leg muscle injury.

They played very very well in their 1-1 in the first leg against Barcelona a week ago, and played just as well in a 2-2 draw against Real Madrid at the weekend.

Messi turned provider for the third, with a spectacular curled through-ball for Alba which he fired past the helpless Sergio Alvarez.

"The connection between Messi and Alba is nothing new, it has been working for years", Valverde said.
